Night Shift Work Not Associated With Cognitive Decline.

Reuters (10/11, Doyle) reported that, according to a study (10/14) published online Sept. 27 in the American Journal of Epidemiology, working the night shift appears not to result in long-term cognitive impairment in middle-aged women. Researchers arrived at this conclusion after analyzing data from the Nurses’ Health Study on some 16,000 middle-aged female nurses.
